The video explains the presence of carbon atoms in the human body, focusing on carbon-14, an isotope used in radiocarbon dating. It describes how carbon-14 forms in the atmosphere and is absorbed by living organisms. The process of radiocarbon dating is detailed, highlighting the decay of carbon-14 into nitrogen-14 and its half-life. The video also covers methods for measuring carbon-14, such as Geiger counters and accelerator mass spectrometry, and discusses challenges like atmospheric changes affecting dating accuracy.
